PARADE FUSS

In the Sept. 29 episode of The Sopranos, the show's mobsters got into a furious debate over Columbus Day observances. Now, there's a real-life dustup over whether castmates Dominic Chianese (Uncle Junior) and Lorraine Bracco (Dr. Melfi) should march in New York's Columbus Day parade. When organizers refused to let them participate  saying Italian-Americans take offense at the HBO show's Mafia stereotyping  ex-mayor Rudy Giuliani told reporters: "I'm a big Sopranos fan. The show is a terrific show, and I would urge some Italian-Americans to be less sensitive... I think we all get beyond it when we just relax more about it. It's just a show."
